Weiwei Yang updated HDFS-11955:
-------------------------------
Attachment: HDFS-11955-HDFS-7240.001.patch
Patch uploaded. This patch fixed following issues
1. REST call for listBucket uses 0 as the default listing length, changed that
to use {{Header#OZONE_DEFAULT_LIST_SIZE}}
2. Oz command line listBucket doesn't support arguments that REST call already
supported, such as listing length, start bucket name and prefix. Added support
of that, usage
*Specify listing result length via command line*
{code}
./bin/hdfs oz -listBucket http://ozone1.fyre.ibm.com:9864/volume-wwei-0 -length
2
{code}
*Specify a prefix to filter the result*
{code}
./bin/hdfs oz -listBucket http://ozone1.fyre.ibm.com:9864/volume-wwei-0 -prefix
bucket1
{code}
*Specify a start bucket name where to start listing from*
{code}
./bin/hdfs oz -listBucket http://ozone1.fyre.ibm.com:9864/volume-wwei-0 -start
bucket2
{code}
3. Added some tests in {{TestBuckets}} and modified this class to use
distributed handler instead of local.
4. {{KeySpaceManagerProtocolServerSideTranslatorPB}} swallows exception if it
is not an expected KSMException in {{exceptionToResponseStatus}}. Added a debug
message to log the exception in KSM server log, otherwise we have no idea what
happened.
Thanks

> HDFS-11779 implements the listBuckets function in ozone server side, the API
> supports several parameters, startKey, count and prefix. But both of them are
> optional for the client side rest API. This jira is to make sure we set
> proper default values in the http request if they are not explicitly set by
> users.
